I'm an intermediate blender user, and I am working on a scene myself. I just don't know how should I achieve the lighting effect in the image on the right below (left one is mine). I also need assistance on how to add volumetrics in this scene. I am using a transparent hdri in my scene.
EDIT:
With help form the comments, I have changed a few settings and achieved close to what I want. The volumetrics (I added a rectangle with a principled volume shader) look good, but I still don't know how to achieve that sharp lighting effect I have shown with arrows in the picture above so I will wait for answers. I haev reached the end of my scene almost, so here's what I have done uptil now:
EDIT 2: After doing some research about this topic, I finally achieved the effect I wanted. Thanks for the help in the comments!
